Using Safe Mode

Safe Mode lets the printer continue to operate in a special limited mode in which it attempts to continue offering
as much functionality as possible despite known issues.
Warning—Potential Damage: Safe Mode is intended as a short‑term workaround and should be used only in
the case of a non‑critical error when a print job must be completed before service can be arranged to repair
the printer. The printer must be returned to standard operating mode before diagnostics can be run or
full‑function printing can continue.
You can enter Safe Mode in one of the following ways:
•
Enable Safe Mode from the Configuration menu, and then POR the printer.
•
Press the Stop and Back keys, and then POR the printer.
Return the printer to standard operating mode to service the printer and return to full‑function printing.
